Conair具有业界最高级的控件2019新万博appmanbetⅩrepresent a dramatic step forward in ease of programming and use, simplified troubleshooting, comprehensive data collection and, of course, accuracy. Those are pretty hefty claims, but TrueBlend gravimetric blenders are not like other blenders you might be evaluating. Let’s take a close look at why.

What Makes a Gravimetric Blender the Best?

使重量搅拌器脱颖而出的关键成分是其控制。

The latest SmartBlend SB-4 control from Conair sets a new standard for ease and precision in blender control for injection-molding and extrusion operations. Accessed through an enlarged and more vivid 7-inch color touchscreen display, the SB-4 control simplifies blending control with friendlier, more intuitive graphics, easier programming and morecomprehensive monitoring and controlfeatures. It also sustains a best-in-industry dosing accuracy of 0.025% for the total batch dispensed, thanks to Conair’s unique “feed forward” dosing algorithm.

这是6件事,最好的重量搅拌机做了:

  1. 使用直观且功能丰富的触摸屏显示简单设置。

    SB-4The home screen display provides realistic graphics, showing current material levels and target-vs-actual dosing for each attached TrueBlend feed hopper, plus information about mixing-chamber material level and mixer blade rotation.The control can manage up to 12 ingredients, dispensed from 12 material bins. That’s 50% more than competitive blenders.

    Set-up is highly intuitive. The operator simply uses the touchscreen to identify the material types – any material can be assigned to any bin – and sets the feeding order. If regrind is a component, simply identify what percentage of the total batch size will be regrind. Then, the control automatically scales in the other materials in the batch to keep the ratio of all ingredients in line with the recipe. It will also reset the blend ratio if the regrind supply runs low or is depleted. Once a recipe is set, it can be stored in the expansive SmartBlend memory, which can accommodate up to 3000 recipes and up to 4000 resins and ingredients under custom names according to whatever system works best for the user.

    控件显示支持12种语言,使用户可以选择他们喜欢的编程和操作的任何语言。即使从不同的员工与系统互动,也可以随时轻松地更改该语言。

    The SB-4 blender control also includes a self-loading option, enabling users to add vacuum receivers to blender hoppers. After plugging them in to the SB-4, users enter parameters through the touchscreen to control up to 12 loaders, as well as 1 pump per blender, so that they can move materials to or from blenders, even using priority loading, if needed. The SB-4 shares the same loader control interface, so no extra operator training is needed.

  2. 通过逐步分配每批来提高给药精度。

    No2018世界杯狗万滚球appis more accurate than a TrueBlend blender thanks to a unique “feed-forward” learning algorithm at the heart of the SB-4 control. Instead of making a single dispense of each ingredient and adjusting for discrepancies in subsequent batches, the SB-4 uses incremental dispenses in each batch, continuously weighing the material and adding a little bit more until the target weight is reached. This approach ensures that all materials are accurate to 0.025% of the batch recipe. In other words, if the total batch is 1000g, it can dose any ingredient to within 0.25 grams of the target.

    另一个主要因素是在分配成分的顺序中。在大多数搅拌机中,分配顺序始于Regrind,然后是天然/处女,然后颜色或添加剂。颜色/添加剂通常是最后一次完成的,以便可以根据已经称重的饮食/天然的适当百分比进行计算。但是,Conair已重新排列标准序列。重新赠款仍然是序列中的第一(因为它始终是总批次的一定百分比,并且已经包含颜色和/或添加剂)。然后,将次要成分分配第二,并尽可能准确地称重,然后对自然成分进行相应调整。通过将批处理精度键入最小的组件,而不是最大的组件,Conair的分配序列可显着提高批处理的一致性和准确性。

    Accuracy is further enhanced by using batch reports (about which more will be presented below) and process control to manage dosing centering and variability. The SB-4 SmartBlend control calculates bothCp, which measures the variability of dosing over time, andCPk,一个值表示可变性曲线在上层和下规范之间的良好程度。这样可以确保将材料以可重复的剂量量分配,并且该量良好地居中在上层和下规格之间。

  3. Enable real-time troubleshooting with dispensing diagnostics and user-defined alarm parameters.

    TheSB-4Smartblend control很容易诊断搅拌机在现实问题-time. You can actually watch a batch being made. When it’s done, you can see the actual amounts that it dosed, the set and actual values in grams and as a percentage of the total batch. You can see the time it took to dispense each material and the number of dispenses it took to reach the final weight. From the control, you can also verify the accuracy of the blender. This is valuable in many situations. You can look at it live and see, for instance, if you have a valve problem or whether there might be some bridging in one of the material bins. And all this data is retrievable: every value for every component in every batch, along with the Cp and CPk data noted above. Just save it to a USB stick or share it over a network to other computers for more in-depth analysis.

    当然,SmartBlend控件还识别出可能发生的其他问题(例如Hopper低材料信号),并根据需要生成警报,以保持混合操作无故障。警报可能是紧急的,需要立即注意,或者被动或仅提供信息。它们也可以通过用户定义的参数进行修改。控件可以跟踪和记录多达100个事件(日期,时间,警报类型),并报告警报日期,时间和错误时间。

  4. 通过按需报告验证混合质量和其他KPI。

    SB-4reporting capabilities screen透明度是Conair开发SB-4控制的数据收集和报告功能的主要目标之一。每个搅拌机都可以制定各种报告,这些报告可用于验证混合质量和一致性,跟踪在给定时间段内的树脂和其他成分的消耗,随着时间的推移跟踪特定食谱的数量,或记录特定的材料零件或客户订单。只需按照控制面板上的“运行报告”按钮或按用户定义的时间表自动运行,就可以按需求收集任何特定于Blender的报告。

  5. Eliminate manual compilation of blender reports with SQL database queries.

    直到最近,获得搅拌器操作的植物范围的视图需要手动汇编所有特定于搅拌机的报告。但是现在,这些报告可以直接从搅拌机直接导出到SQL(结构化查询语言)服务器,通过从搅拌机到网络中心的以太网连接。这样,上面讨论的所有数据都直接流入SQL数据库。自动加载并格式化到该数据库中后,您可以使用Conair创建的数据库查询或编写自己的数据库来运行所需的报告。可以构造查询以报告几乎所有内容 - 就像过去90天中使用的聚乙烯宽度一样,或者与周一第二班次乘以模制细胞#5中的着色剂量一样具体。

  6. Manage data on any device using the Industrial Internet of Things.

    当Conair的时间SmartServices portalwas first introduced at NPE 2018, one of the first families of equipment connected to it were the TrueBlend blenders. SmartServices is a web-based portal, supported by cloud-based data processing capabilities. It helps plastics processors manage data generated by dozens or even hundreds of pieces of plant equipment — blending, drying, temperature controls and more – and turn it into actionable information.

    用户可以使用SmartServices来完成上面讨论的所有SQL报告,包括树脂总计,批处理记录,CP/CPK信息,警报和所有其他数据。所有这些都可以在SmartServices中的报告功能下运行。因为它是基于Web的门户,因此您可以在拥有Internet连接的任何地方使用它。

    最有用的功能之一是能够建立关键绩效指标(KPI)for connected equipment. For blenders, that might be batch hopper weight, how many pounds per hour the blender processes, or actual percentage of a particular ingredient dispensed. But there are as many as 60 different measurements that can be collected from each blender – all stored in the SmartServices cloud. You can also create alerts built around specific KPIs or custom performance thresholds, and tell the portal to notify designated team members (by phone or email) if variances occur.

    For instance, in a blow molding operation, the parison length may be very sensitive to how much regrind is introduced in the material mix. One of your KPI’s could be designated as regrind percentage, with high and low set points. If regrind percentage drifts outside the setpoint window, an alert would be generated and sent to designated team members.

    您还可以通过登录门户并单击“机器控制”按钮来远程控制单个机器。如果出现问题并且关键设置人员异地,则可以提醒他们,并可以从任何地方登录SmartServices,以进行必要的调整,就像他们站在机器控制面板前一样。

Control systems are key when choosing the best gravimetric blender

Whether the SB-4 Smart Blend control system is used alone or augmented by the capabilities of SmartServices, it is the most significant differentiator for TrueBlend blenders versus competitive systems. It delivers not only the highest levels of accuracy, but also ease-of-use that is second to none, and data-collection and reporting capabilities – alone, through SQL databases, or with the SmartServices cloud – that give users a fully transparent view of everything going on with the blender so that they can operate at maximum quality and efficiency with minimal downtime.
